Harken LOUP S 3139 User manual

Loup®Strength
Loup strength will vary depending on: Configuration – One configuration may be more than twice as strong as another. Carefully match strength requirements to the
configuration and corresponding SWL shown in the chart below. Attachment Points – Determine weakest link in the attachment chain. Is it the block? The Loup? The
padeye? Consult chart below for padeye loading at various angles. Condition of Attachment – Loup must attach to round bails or radiused corners. Sharp, rough edges
or corners will cut into Loups, reducing their strength over time. Age of Loup – Strength of Loup is based on their being in like new condition. See chart below.

Even when bail is aligned with load, padeye strength will vary depending on load angle—see below.
WARNING! Strictly follow all instructions to avoid an accident, damage to your vessel,
personal injury or death. See www.harken.com/manuals for additional safety information. = Incorrect. Avoid to prevent accidents.
WARNING! Load applied sideways to the bail greatly
reduces the strength. Always align padeye bail to load
for maximum strength to prevent breakage below

Attaching Loups®to Blocks
WARNING! Block may break suddenly if attached incorrectly. Before attaching Loup you must understand block manufac-
turer's directed method of attachment. Some blocks are designed to secure Loup to head and others to attach Loup through
center of sheave or to protrusions coming out from center of sheave. Attaching Loups improperly may cause an accident.
Harken Black Magic®Loop Block
Harken Grand Prix High-Load Snatch Block
WARNING! Attaching Loup to block head will
considerably weaken block so it can easily break
under load. Attach Loups only to thimble at
sheave center.
Attaching to Blocks or Hardware
Harken®Straphead Block
Attach Loup to head only
if you are sure that it is a
Harken Straphead block.
Harken Straphead blocks
have two screws in head
(see photo at right).
Screws
WARNING! If Loups are stacked they will push outward
on block sideplates when load is applied, causing block
to break especially if crosspin is held using a cotter pin.
This can cause an accident. Make sure Loup can lie
side-by-side.
Thimble
Mouth
Make sure Loup will lie, side-
by-side between Loup and
sheave. Loups will settle and
flatten when load is applied.
If Loup is stacked (one strand
on top of the other) even a
small amount, line can push
outward and break sideplate.
WARNING! Attaching line to block head will consider-
ably weaken block so it can easily break under load.
Attach loop/lashing only through mouth of sheave.
Do not attach
to head

Put a figure 8 stop knot in
one end of the lashing line
and pass it into the hole
in the bone.
Pass one end of the Loup
into the other. Slip the
Dogbone into end so it
is captured as shown.
Tie a single overhand knot
around each outer Loup.
Don’t draw the legs of the
Loups together; let them
assume their loaded
position.
Pass the end of the line
back through the hole
in the bone and tie a
figure 8 stop knot. Use
a hot knife to trim ends.
Attaching Dogbone to Loup®
Harken equipment is designed for minimal maintenance, but some maintenance
is required to give the best service and to comply with the Harken limited warranty.
Cleaning: Flush blocks and loops/high strength lashing lines thoroughly with fresh
water. Periodically, disassemble the blocks and clean with detergent and fresh water.
When assembling block, make sure screws and holes are dry. Use blue Loctite®to
secure screw before assembling.
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can
result in discoloration of part and is not covered under the Harken warranty.
Maintenance
For additional safety, maintenance and warranty information see www.harken.com/
manuals or the Harken®catalog.
Inspect
WARNING! Hardware and attaching Loups can gradually
lose strength from wear and UV rays. Inspect parts often
and during long passages.
WARNING! Loups may degrade without showing obvious signs
and break under load. Replace all Loups and lashings every
year or if there is any sign of wear, UV-damage, fatigue or
strand separation. If in doubt replace. Consult chart to match
strength of Loup/lashing to block and load.
You must periodically inspect Loups and head lashings for signs
of UV damage or wear. Be sure to pull Loup out of block mouth
and inspect carefully for any sign of wear, UV damage, fatigue or
strand separation. The Loup's outer jacket protects the inner core,
but can become damaged from prolonged UV exposure. Loups
have colored tracers that are designed to fade after prolonged UV
exposure. If tracers appear faded, rub them with your fingernail. If
flecks become fuzzy the Loup should be replaced. Inspect Loups
often for signs of chafing, especially where they rub on edges.
Anchor Point Chafing or Cutting
Attach Loups only to round bails such as those found on padeyes
or pins. Sharp edges such as those found in many perforated
toerails will cut into Loups severely weakening them. If a Loup is
attached to a plate, the edges must be rounded so that they are not
damaged. The thickness of the plate must be at least 1/4" to avoid
damaging the Loup.
WARNING: Loups or lashings running over a sharp edge can
cause part to break under load. Secure to items with rounded
edges only.
Warranty
Hardware and attaching Loups can gradually lose strength from wear
and UV rays. Inspect parts often and and during long passages.
